Abstract
This invention relates to a method of treating a gaseous mixture by adsorption making use of at least one group of three adsorbers which operate in three phases, viz. a high pressure production phase, a first adsorber regeneration phase and re-pressurization phase, and the invention consists in providing a balancing between a first adsorber and a second adsorber which precedes a balancing between said first adsorber and a buffer container: the de-pressurization which occurs in the said regeneration phase includes an additional de-pressuration which extends over the whole of the de-pressurization phase from a high production pressure to a low cleansing pressure and which takes place in the direction opposite the direction of production.
